Possible inefficiency in encode.c
Hi,
I am very new to Theora, having just started working through the code a few
weeks ago.
I am working on a requantization tool to reduce bit rates, hopefully on the
fly, for some video conferencing work.
As I was working through the encoding phase I noticed this line in encode.c:
for(ti=_enc->dct_token_offs[pli][zzi];ti<ndct_tokens;ti++){
It's around line 804, but I am

This is a new "feature" in Mac OS 10.6. I am not even sure what it''s trying
to accomplish but it gets upset

Theora Fast Quality Reduction Transcoding
Hi.
I have been working on a tool whose goal is to reduce the bit rate of theora
video by decoding to DCT coefficients, reducing the entropy of the
coefficients, and re-tokenizing the stream.
I have successfully used the decoder source to extract the DCT coefficients
for each block, and I am able to capture any and all relevant information
about where the block of coefficients falls in the
